I'm kind of new to this, too, but I know that Macromedia Dreamweaver MX or later is great for easily generating javascript, pull-down menus....It's easy, relatively fast, you don't have to really know any scripting, and the menus look great!
I used to shop around for pull-down menu scripts as well, until I found and learned how to use Dreamweaver. I highly recommend you get yourself a copy.
Hope this helps.......R.J.
